*Hey guys! My mind is blown at what this little device can do 🙂 Let me
know if you got any ideas from these experiments, and if you liked what you
saw? Thanks for watching, subscribing, and I’ll see you in 10 days when we
get back in town with the videos on how to make it!! :D*﻿

I watch these videos, and I’m like,”How is it he hasn’t been killed yet?”
He plays with flammable hydrogen, liquid nitrogen, eats dry ice, make a
stick welder out of a microwave, and melts rocks into lava using flashlight
batteries.﻿

Absolutely insane! It blows my mind that something like this isn’t widely
used. I mean you made lava…LAVA….with nothing more than household
stuff! I’m somehow convinced that that power output is like nothing before
and could benefit mankind. I however don’t know if scaling it would be
practical or even feasible.﻿

1:20 ‘ Surprisingly, the outside is still cool enough that i can pick it up
bare handed..’ HOW ? I mean, i watched mythbusters doing that but can
anyone explain me why doesnt that burn your hand. Since it is in the
melting point, shouldnt it be extremely high that can burn anything that
touched to it ?﻿

Hey grant! I’m speaking on behalf of the whole MTG SDM community, and we
are growing stubbornly slowly. We could really use some advice or help, but
please, don’t fell that you need to. But if you could help us out, it would
mean a lot to us!

I ordered a couple of carbon rods but mine don’t arc nearly as well as
yours do. By the time they arc they are practically touching. Do I need to
shape the tips? Any idea what I’m doing wrong? Thanks! ﻿

+Grant Thompson – “The King of Random” I’m going to try and modify this
and retrofit it to my coffee can forge for blacksmithing. I’ve been doing a
little reading and found a couple places that said graphite rods could be
used also. Would solid graphite artist’s pencil work or would that type of
graphite be too soft? I have a couple that are roughly the same diameter of
the carbon rods. Now, would larger rods, or a higher electrical output
accommodate a larger chamber size? Did you use the same wires that you used
on the welder or did you tap the MOTs and use larger wires to connect to
the vise grips? One last question, would the furnace be capable of heating
sections of a larger piece? I WILL be making this arc furnace and would
really appreciate your input.﻿

I noticed your arms weren’t covered while you demonstrated the carbon arc.
I studied them and found they do emit UV and can sunburn exposed skin.
Carbon arc was used for lighting outdoor events way back before good large
lamps were available. We should never look at a carbon arc without welding
equipment. It is remarkable the high temperatures you achieved with them. I
am glad you presented this experiment in such a clean and to the point
format.﻿

I would love to see if you could get more detailed castings from the
copper. I have an idea for some custom coins and I’m not sure if it’s
possible to get rid of all those bubbles I saw on your copper casting.﻿
